11. 11/15 Heavy Ion Source KRION-6T Nuclotron-NICA Assembling of electron/ion optics system: view from the “ion extraction” side. Superconducting test coil (L=19 cm, 32 layers of SC wire) : preparation for testing in a liquid helium. Magnetic field (T) versus current (A) for SC solenoids; experimental and expected data. 1) 26 layers (green line, 21 Jan.’11) – 7.41T at I_crit.=131 A (experimental data); 2) 32 layers (top green line, 25 Apr.’11) – 7.81T at I_crit=114 A (experimental data); 3) red line: critical current for SC wire according it’s manufacturer data; 4) blue line: expected for Krion-6T ESIS – 22 layers, L=120 cm, B=6 T at I_working=118 A. Should be ready in September 2011.
